Sarah Ferguson, Duchess of York, will be part of Oprah Winfrey’s kingdom soon after the talkshow host’s new OWN channel bows in January.

Ferguson will be the subject of a six-part doc, “Finding Sarah,” airing on OWN in the first quarter of 2011. The long-awaited cabler is set to bow Jan. 1.

Ferguson show aims to “share with our viewers her personal struggle to rebuild her life,” OWN chief creative officer Lisa Erspamer said. “With the help of experts Dr. Phil McGraw, Suze Orman, Martha Beck and others, the duchess will open up about her recent public troubles and explore her lifelong battles with weight, relationships and finances.”
